Nice work on these =). You got the torso and the legs pretty well, proportions are also better than the first time.

The biggest issues I can find with the second batch are:

1)The necks, which are a bit too tick, try to make them a bit slimmer.

2) The arms are well done and proportioned, the only issue is the way you connect them to the torso which is a bit too stiff. You have to understand that the "sphere" on the top of the arm is a semplification of the soulder, but they are not really "locked" on the torso and they are free to move to a certain degree. So when you raise the arm over the head or to a horizontal position, you have to put the sphere higher and move it around.
